随着城市地铁的大量修建，尤其是地铁车站多采用明挖法施工就带来了很多深基坑的问题。每一个深基坑所处的地质条件和水文条件各不相同，因此，进行深基坑的监测和变形研究就变得尤为重要。本文以昆明轨道交通某深基坑作为研究对象，根据现场的实测数据分析了该地区泥炭土质在施工过程中的支撑轴力随着开挖的变形规律，通过这些规律认识昆明地区深基坑工程的特点，为该地区以后的类似工程提供一些经验。%Subway construction is increasing in cities, and subway station usually adopts cut and cover tunneling, causing a lot of deep foundation pit problems. The geological conditions and hydrological conditions of different deep foundation pits are different, so the monitoring and deformation research of deep foundation pit is very important. Taking a deep foundation pit in rail transit in Kunming as the research object, the deformation rule of the support axial force of peat soil in this region with the excavation is analyzed based on the measured data of the construction site. Through these rules, we can understand the characteristics of the deep foundation pit engineering in Kunming, and provide some experience for similar projects in the future.
